1998 Deville =========== 1) Why is my 98 Deville randomly idling at 1300-1400rpm? - turn it off for 5 seconds or 5 hours, maybe it will continue.. maybe not. CODES: PCM P0122, P1122 IPC B1552 PZM B0533 2) Why did water start to pour into the front passenger side footwell this week...

I usually show 14.2v on the dashboard voltmeter. As of yesterday, it shows 13.6v. And every 30 seconds, it drops to 12.0v for about 5 seconds. IPC B1552 is the only code. What do you think?

Trying to change the pads, but the pistons won't retract. The Firestone people said that the pistons or bores may be corroded, so you can't screw them fully open. Anyone have suggestions? Thanks.

1998 Deville gave "low a/c coolant" message recently. Now won't go from ECON to AUTO and stay there. Looks like time for a recharge. But my cheesy gauge says 35psi in the system now. What is the correct psi?

1998 DEVILLE's idle is loco after Emissions Test =================================== Immediately after our yearly emissions test (this year they hooked up the scanning computer), idling problems started. Last night it was idling at 2600rpm when I parked in my garage after a 10 mile drive...

How do I access the tail lights to replace 2 dead 'uns?

My '98 Deville occasionally goes into "hibernation mode" after being parked. Meaning: battery power is evident in the trunk closer, but the dome light is dead upon opening the door and the car is nonresponsive to the remote... ...until you turn the key to ON. Then everything wakes up...

For a month or so, it seems that the ABS braking system is constantly activated. The brakes are pulsing with every stop. My mechanic said the pads are fine, and he's seen the Deville ABS stick before. What can be done???

My 98's turn signals went screwy yesterday and pooped out over about an hour's time. At first, they'd blink too fast... then would only work if you held the stick just so... now neither work at all. I got a replacement switch at Advance Auto. I need to remove the steering wheel (I have...

I'm losing at least a quart every couple hundred miles. There's a coating of oil on the lower oil pan (1998 Deville), but only a few drops on the driveway... so it's leaking when running. My mechanic said that the upper pan is prone to leaking and should have been recalled. Supposedly...

Maybe 20% of the time, my 98 Deville seems dead. Won't open for the keyless entry remote. If I open the door with the key... still dead. No power locks, etc. If I turn the ignition to accessory or ON... presto! Back to life. What's going on?????
